Hood clearance Question

I have a 1967 Barracuda and am setup with a 1407 Edlebrock carb. with Airgap manifold and was thinking about using a carb spacer but with engine not installed yet I don't know how tall and for that matter if there is a particular type that would work best with my engine. Reason for considering is the common issue of fuel boiling off in carb.

Set up of my engine:
2002 360 Magnum
750 CFM Edelbrock carb. mech secondary
Airgap intake mild porting
Ported Cast iron Magnum heads Stock valves
Comp Cams 900-5,200 RPM Operating Range 210/220 Duration at .050". 112 Degree Lobe Separation Angle 0.512/0.512 Valve Lift
Stock Compression
